In one aspect, the present disclosure provides methods of introducing asingle locus conversion conferring one or more desired trait(s) into thebean plant HMX0175722, and plants or parts including pods and/or seedsobtained from such methods. In another aspect, the present disclosureprovides methods of modifying a single locus and conferring one or moredesired trait(s) into the bean plant HMX0175722, and plants or partsincluding pods and/or seeds, and/or bean, obtained from such methods.The desired trait(s) may be, but not exclusively, conferred by a singlelocus that contains a single and/or multiple gene(s). In someembodiments, the gene is a dominant allele. In some embodiments, thegene is a partially dominant allele. In some embodiments, the gene is arecessive allele. In some embodiments, the gene or genes will confer ormodify such traits, including but not limited to male sterility,herbicide resistance, insect resistance, resistance for bacterial,fungal, mycoplasma or viral disease, enhanced plant quality such asimproved drought or salt tolerance, water-stress tolerance, improvedstandability, enhanced plant vigor, improved shelf life, delayedsenescence or controlled ripening, enhanced nutritional quality such asincreased sugar content or increased sweetness, increased texture,flavor and aroma, improved pod length and/or size, protection for color,pod shape, uniformity, length or diameter, refinement or depth, lodgingresistance, yield and recovery, improve fresh cut application, specificaromatic compounds, specific volatiles, flesh texture and specificnutritional components. For the present disclosure and the skilledartisan, disease is understood to include, but not limited to fungaldiseases, viral diseases, bacterial diseases, mycoplasma diseases, orother plant pathogenic diseases and a disease resistant plant willencompass a plant resistant to fungal, viral, bacterial, mycoplasma, andother plant pathogens. In one aspect, the gene or genes may be naturallyoccurring bean gene(s) and/or spontaneous or induced mutations(s). Inanother aspect, genes are mutated, modified, genetically engineeredthrough the use of New Breeding Techniques described herein. In someembodiments, the method for introducing the desired trait(s) into beanplant HMX0175722 is a backcrossing process by making use of a series ofbackcrosses to bean plant HMX0175722 or at least one of the parentalinbred lines of bean plant designated HMX0175722, which the desiredtrait(s) is maintained by selection. Bean plant HMX0175722 or at leastone of the parental inbred lines of bean plant designated HMX0175722possesses the desired trait(s) by the backcrossing process, and thedesired trait(s) is inherited by the bean progeny plants by conventionalbreeding techniques known to breeders of ordinary skill in the art. Thesingle gene converted plants or single locus converted plants that canbe obtained by the methods are included in the present disclosure.

When dealing with a gene that has been modified, for example through NewBreeding Techniques, the trait (genetic modification) could be directlymodified into the newly developed bean plant and/or at least one of theparental inbred lines of bean plant HMX0175722. Alternatively, if thetrait is not modified into each newly developed bean plant and/or atleast one of the parent lines of bean plant HMX0175722, another typicalmethod used by breeders of ordinary skill in the art to incorporate themodified gene is to take a line already carrying the modified gene andto use such line as a donor line to transfer the modified gene into thenewly developed bean plant and/or at least one of the parent lines ofthe newly developed plant. The same would apply for a naturallyoccurring trait or one arising from spontaneous or induced mutations.

In some embodiments, the backcross breeding process of bean plantHMX0175722 comprises (a) crossing one of the parental inbred line plantsof bean plant HMX0175722 with plants of another line that comprise thedesired trait(s) to produce F₁ progeny plants. In some embodiments, theprocess further comprises (b) selecting the F₁ progeny plants that havethe desired trait(s). In some embodiments, the process further comprises(c) crossing the selected F₁ progeny plants with the parental inbredbean lines of bean HMX0175722 plants to produce backcross progenyplants. In some embodiments, the process further comprises (d) selectingfor backcross progeny plants that have the desired trait(s) andessentially all of the physiological and morphological characteristicsof the bean parental inbred line of bean plant HMX0175722 to produceselected backcross progeny plants.

The bean plants or seed produced by themethods are also part of the disclosure, as are the bean HMX0175722plants that comprised the desired trait. Backcrossing breeding methods,well known to one skilled in the art of plant breeding will be furtherdeveloped in subsequent parts of the specification.

An embodiment of this disclosure is a method of making a backcrossconversion of bean plant HMX0175722. In some embodiments, the methodcomprises crossing bean plant HMX0175722 with a donor plant comprisingan induced gene mutation(s), a naturally occurring gene mutation(s) or agene(s) and/or sequence(s) modified through New Breeding Techniquesconferring one or more desired traits to produce F₁ progeny plants. Insome embodiments, the method further comprises selecting an F₁ progenyplant comprising the naturally occurring gene mutation(s), induced genemutation(s) or gene(s) and/or sequences(s) modified through New BreedingTechniques conferring the one or more desired traits. In someembodiments, the method further comprises backcrossing the selectedprogeny plant to the bean plant HMX0175722. This method may furthercomprise the step of obtaining a molecular marker profile of the beanplant HMX0175722 and using the molecular marker profile to select forthe progeny plant with the desired trait and the molecular markerprofile of the bean plant HMX0175722. In some embodiments, this methodfurther comprises crossing the backcross progeny plant of the parentalbean plant HMX0175722 containing the naturally occurring genemutation(s), the induced gene mutation(s) or the gene(s) and orsequences modified through New Breeding Techniques conferring the one ormore desired traits with the second parental bean plants of bean plantHMX0175722 in order to produce the bean plant HMX0175722 comprising thenaturally occurring gene mutation(s), the induced gene mutation(s) orthe gene(s) and/or sequences modified through New Breeding Techniquesconferring the one or more desired traits. The plants or parts thereofproduced by such methods are also part of the present disclosure.

In some embodiments of the disclosure, the number of loci that may betransferred and/or backcrossed into the bean plant HMX0175722 is atleast 1, 2, 3, 4, 5, or more.

A single locus may contain several genes. A single locus conversion alsoallows for making one or more site specific changes to the plant genome,such as, without limitation, one or more nucleotide changes, deletions,insertions, substitutions, etc. In some embodiments, the single locusconversion is performed by genome editing, a.k.a. genome editing withengineered nucleases (GEEN). In some embodiments, the genome editingcomprises using one or more engineered nucleases. In some embodiments,the engineered nucleases include, but are not limited to Zinc fingernucleases (ZFNs), Transcription Activator-Like Effector Nucleases(TALENs), the CRISPR/Cas system (using such as Cas9, Cas12a/Cpf1,Cas13/C2c2, CasX and CasY), engineered meganuclease, engineered homingendonucleases and endonucleases for DNA guided genome editing (Gao etal., Nature Biotechnology (2016), doi: 10.1038/nbt.3547). In someembodiments, the single locus conversion changes one or severalnucleotides of the plant genome. Such genome editing techniques are someof the techniques now known by the person skilled in the art and hereinare collectively referred to as “New Breeding Techniques”. In someembodiments, one or more above-mentioned genome editing methods aredirectly applied on a plant of the present disclosure, rather than onthe parental bean lines of HMX0175722. Accordingly, a cell containing anedited genome, or a plant part containing such cell can be isolated andused to regenerate a novel plant which has a new trait conferred by saidgenome editing, and essentially all of the physiological andmorphological characteristics of bean plant HMX0175722.

The disclosure further provides methods for developing bean plants in abean plant breeding program using plant breeding techniques includingbut not limited to, recurrent selection, backcrossing, pedigreebreeding, genomic selection, molecular marker (Isozyme Electrophoresis,Restriction Fragment Length Polymorphisms (RFLPs), Randomly AmplifiedPolymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reactions(AP-PCRs), DNA Amplification Fingerprintings (DAFs), SequenceCharacterized Amplified Regions (SCARs), Amplified Fragment LengthPolymorphisms (AFLPs), and Simple Sequence Repeats (SSRs) which are alsoreferred to as Microsatellites, Single Nucleotide Polymorphisms (SNPs),enhanced selection, genetic markers, enhanced selection andtransformation. Seeds, pods, bean plants, and parts thereof produced bysuch breeding methods are also part of the disclosure.

The disclosure also relates to variants, mutants and trivialmodifications of the bean plant HMX0175722, parts thereof or parentalinbred lines thereof. Variants, mutants and trivial modifications ofbean plant HMX0175722 and parts (such as seeds, pods, beans etc.)thereof can be generated by methods available to one skilled in the art,including but not limited to, mutagenesis (e.g., chemical mutagenesis,radiation mutagenesis, transposon mutagenesis, insertional mutagenesis,signature tagged mutagenesis, site-directed mutagenesis, and naturalmutagenesis), knock-outs/knock-ins, antisense oligonucleotides, RNAinterference and other techniques such as the New Breeding Techniquesdescribed herein. For more information of mutagenesis in plants, such asagents or protocols, see Acquaah et al. (Principles of plant geneticsand breeding, Wiley-Blackwell, 2007, ISBN 1405136464, 9781405136464,which is herein incorporated by reference in its entity).

The disclosure also relates to a mutagenized population of the beanplant HMX0175722 and methods of using such populations. In someembodiments, the mutagenized population can be used in screening for newbean plants which comprise essentially one or more of or all themorphological and physiological characteristics of bean plantHMX0175722. In some embodiments, the new bean plants obtained from thescreening process comprise essentially all of the morphological andphysiological characteristics of the bean plant HMX0175722, and one ormore additional or different morphological and physiologicalcharacteristics that the bean plant HMX0175722 does not have.

This disclosure is also directed to methods for producing a bean plantby crossing a first parent bean plant with a second parent bean plant,wherein either the first or second parent bean plant is a bean plant ofHMX0175722. Further, both first and second parent bean plants can comefrom the bean plant HMX0175722. Further, the bean plant HMX0175722 canbe self-pollinated i.e., the pollen of a bean plant HMX0175722 canpollinate the ovule of the same bean plant HMX0175722. When crossed withanother bean plant, a seed is produced. Such methods of hybridizationand self-pollination are well known to those skilled in the art ofbreeding.

A bean plant such as one of the parental lines of bean plant HMX0175722has been produced through several cycles of self-pollination and istherefore to be considered as a homozygous line. An inbred line can alsobe produced though the dihaploid system which involves doubling thechromosomes from a haploid plant or embryo thus resulting in an inbredline that is genetically stable (homozygous) and can be reproducedwithout altering the inbred line. Haploid plants could be obtained fromhaploid embryos that might be produced from microspores, pollen, anthercultures or ovary cultures or spontaneous haploidy. The haploid embryosmay then be doubled by chemical treatments such as by colchicine or bedoubled autonomously. The haploid embryos may also be grown into haploidplants and treated to induce the chromosome doubling. In either case,fertile homozygous plants may be obtained. A variety is classicallycreated through the fertilization of an ovule from an inbred parentalline by the pollen of another, different inbred parental line. Due tothe homozygous state of the inbred line, the produced gametes carry acopy of each parental chromosome. As both the ovule and the pollen bringa copy of the arrangement and organization of the genes present in theparental lines, the genome of each parental line is present in theresulting F₁, theoretically in the arrangement and organization createdby the plant breeder in the original parental line.

As long as the homozygosity of the parental lines is maintained, theresulting cross shall be stable. The F₁ is then a combination ofphenotypic characteristics issued from two arrangement and organizationof genes, both created by a person skilled in the art through thebreeding process.

Still further, this disclosure is also directed to methods for producinga bean plant HMX0175722-derived bean plant by crossing bean plantHMX0175722 with a second bean plant. In some embodiments, the methodsfurther comprise obtaining a progeny seed from the cross. In someembodiments, the methods further comprise growing the progeny seed, andpossibly repeating the crossing and growing steps with the bean plantHMX0175722 derived plant from 0 to 7 or more times. Thus, any suchmethods using the bean plant HMX0175722 are part of this disclosure:selfing, backcrosses, production, crosses to populations, and the like.All plants produced using bean plant HMX0175722 as a parent are withinthe scope of this disclosure, including plants derived from bean plantHMX0175722.

Essentially all of the physiological and morphological characteristics:A plant having essentially all of the physiological and morphologicalcharacteristics means a plant having all of the physiological andmorphological characteristics of a plant of the present disclosure,except for example, additional traits and/or mutations which do notmaterially affect the plant of the present disclosure, or, a desiredcharacteristic(s), which can be indirectly obtained from another plantpossessing at least one single locus conversion via a conventionalbreeding program (such as backcross breeding) or directly obtained byintroduction of at least one single locus conversion via New BreedingTechniques. In some embodiments, one of the non-limiting examples for aplant having (and/or comprising) essentially all of the physiologicaland morphological characteristics shall be a plant having all of thephysiological and morphological characteristics of a plant of thepresent disclosure other than desired, additionaltrait(s)/characteristic(s) conferred by a single locus conversionincluding, but not limited to, a converted or modified gene.

Field holding ability: A bean plant that has field holding ability meansa plant having pods that remain smooth and retain their color even afterthe seed is almost fully developed.

Immunity to disease(s) and or insect(s): A bean plant which is notsubject to attack or infection by specific disease(s) and or insect(s)is considered immune.

Intermediate resistance to disease(s) and or insect(s): A bean plantthat restricts the growth and development of specific disease(s) and orinsect(s), but may exhibit a greater range of symptoms or damagecompared to resistant plants. Intermediate resistant plants will usuallyshow less severe symptoms or damage than susceptible plant varietieswhen grown under similar environmental conditions and/or specificdisease(s) and or insect(s) pressure, but may have heavy damage underheavy pressure. Intermediate resistant bean plants are not immune to thedisease(s) and or insect(s).

New Breeding Techniques: New breeding techniques (NBTs) are said ofvarious new technologies developed and/or used to create newcharacteristics in plants through genetic variation, the aim beingtargeted mutagenesis, that is targeted introduction of new genes or genesilencing. The following breeding techniques are within the scope ofNBTs: targeted sequence changes facilitated through the use of Zincfinger nuclease (ZFN) technology (ZFN-1, ZFN-2 and ZFN-3, see U.S. Pat.No. 9,145,565, incorporated by reference in its entirety),Oligonucleotide directed mutagenesis (ODM, a.k.a., site-directedmutagenesis), Cisgenesis and intragenesis, epigenetic approaches such asRNA-dependent DNA methylation (RdDM, which does not necessarily changenucleotide sequence but can change the biological activity of thesequence), Grafting (on GM rootstock), Reverse breeding,Agro-infiltration for transient gene expression (agro-infiltration“sensu stricto”, agro-inoculation, floral dip), genome editing withendonucleases such as chemical nucleases, meganucleases, ZFNs, andTranscription Activator-Like Effector Nucleases (TALEN5, see U.S. Pat.Nos. 8,586,363 and 9,181,535, incorporated by reference in theirentireties), the CRISPR/Cas system (using such as Cas9, Cas12a/Cpf1,Cas13/C2c2, CasX and CasY; also see U.S. Pat. Nos. 8,697,359; 8,771,945;8,795,965; 8,865,406; 8,871,445; 8,889,356; 8,895,308; 8,906,616;8,932,814; 8,945,839; 8,993,233; and 8,999,641, which are all herebyincorporated by reference), engineered meganuclease, engineered homingendonucleases, DNA guided genome editing (Gao et al., NatureBiotechnology (2016), doi: 10.1038/nbt.3547, incorporated by referencein its entirety), and Synthetic genomics. A major part of today'stargeted genome editing, another designation for New BreedingTechniques, is the applications to induce a DNA double strand break(DSB) at a selected location in the genome where the modification isintended. Directed repair of the DSB allows for targeted genome editing.Such applications can be utilized to generate mutations (e.g., targetedmutations or precise native gene editing) as well as precise insertionof genes (e.g., cisgenes, intragenes, or transgenes). The applicationsleading to mutations are often identified as site-directed nuclease(SDN) technology, such as SDN1, SDN2 and SDN3. For SDN1, the outcome isa targeted, non-specific genetic deletion mutation: the position of theDNA DSB is precisely selected, but the DNA repair by the host cell israndom and results in small nucleotide deletions, additions orsubstitutions. For SDN2, a SDN is used to generate a targeted DSB and aDNA repair template (a short DNA sequence identical to the targeted DSBDNA sequence except for one or a few nucleotide changes) is used torepair the DSB: this results in a targeted and predetermined pointmutation in the desired gene of interest. As to the SDN3, the SDN isused along with a DNA repair template that contains new DNA sequence(e.g. gene). The outcome of the technology would be the integration ofthat DNA sequence into the plant genome. The most likely applicationillustrating the use of SDN3 would be the insertion of cisgenic,intragenic, or transgenic expression cassettes at a selected genomelocation. A complete description of each of these techniques can befound in the report made by the Joint Research Center (JRC) Institutefor Prospective Technological Studies of the European Commission in 2011and titled “New plant breeding techniques—State-of-the-art and prospectsfor commercial development”, which is incorporated by reference in itsentirety.

Machine harvestable bush: A machine harvestable bush means a bean plantthat stands with pods off the ground. The pods can be removed by amachine from the plant without leaves and other plant parts.

Maturity date: Plants are considered mature when the pods have reachedtheir maximum allowable seed size and sieve size for the specific useintended. This can vary for each end user, e.g., processing at differentstages of maturity would be required for different types of consumerbeans, such as “whole pack,” “cut,” or “french style.” The number ofdays is calculated from a relative planting date which depends on daylength, heat units, and other environmental factors.

Bean Plants

Phaseolus vulgaris, also known as the common bean and French bean, is aherbaceous annual plant grown worldwide for its edible dry seeds orunripe fruit (both commonly called beans). The main categories of commonbeans, on the basis of use, are dry beans (seeds harvested at completematurity), snap beans (tender pods with reduced fiber harvested beforethe seed development phase) and shell (shelled) beans (seeds harvestedat physiological maturity). Its leaf is also occasionally used as avegetable and the straw as fodder. Its botanical classification, alongwith other Phaseolus species, is as a member of the legume familyFabaceae. Like most members of this family, common beans acquire thenitrogen they require through an association with rhizobia, which arenitrogen-fixing bacteria.

Wild members of the species have a climbing habit, but many cultivarsare classified either as bush beans or dwarf beans, or as pole beans orclimbing beans, depending on their style of growth. These include thekidney bean, the navy bean, the pinto bean, and the wax bean. The othermajor types of commercially grown bean are the runner bean (Phaseoluscoccineus) and the broad bean (Vicia faba). There are numerous varietiesof P. vulgaris, including many common garden types (i.e., garden bean)such as pole, snap, string, and bush beans. It is called French bean,haricot bean, or kidney bean in various countries; in the United States,however, kidney bean refers to a specific type that is definitelykidney-shaped and is red, dark red, or white. Green beans, anasazibeans, navy beans, black beans, northern beans, kidney beans, pintobeans, and cannellini beans are all varieties of the species. Somevarieties of the common bean are grown only for the dry seeds, some onlyfor the edible immature pods, and others for the seeds, either immatureor mature.

Many well-known bean cultivars and varieties belong to Phaseolusvulgaris. An exemplary list of the bean cultivars and varieties, but arenot limited to, are as follows: Anasazi bean, appaloosa bean, blackturtle bean, calypso bean, cranberry bean, dragon tongue bean, flageoletbean, kidney bean (a.k.a. red bean), pea bean, pink bean, pinto bean,rattlesnake bean, white bean (a.k.a. navy bean or haricot bean’including cannellini), yellow bean (a.k.a. Sinaloa Azufrado, Sulphur,Mayacoba, Peruano, Canary), and tongue of fire bean (a.k.a. Horto)

In bean, these important traits may include increased fresh pod yield,higher seed yield, improved color, resistance to diseases and insects,better stems and roots, tolerance to drought and heat, better standingability in the field, better uniformity, and better agronomic quality.With mechanical harvesting of many crops, uniformity of plantcharacteristics such as germination and stand establishment, growthrate, maturity and plant height is important.

In some embodiments, particularly desirable traits that may beincorporated by this disclosure are improved resistance to differentviral, fungal, and bacterial pathogens. Important diseases include butare not limited to fungi such as Uromyces appendiculatus (rust),Colletotrichum lindemuthianum (anthracnose), virus such as BCMV (beancommon mosaic virus), BCTV (bean curly top virus), bacteria such asPseudomonas (Pseudomonas savastanoi pv. Phaseolicola (halo blight),Pseudomonas syringae pv. Syringae (bacterial brown spot)) or Xanthomonas(Xanthomonas axonopodis pv. Phaseoli (common blight). Improvedresistance to insect pests is another desirable trait that may beincorporated into new garden plants developed by this disclosure.

Bean Breeding

The goal of bean breeding is to develop new, unique and superior beanplant and hybrids. The breeder initially selects and crosses two or moreparental lines, followed by repeated selfing and selection, producingmany new genetic combinations. Another method used to develop new,unique and superior bean plant occurs when the breeder selects andcrosses two or more parental lines followed by haploid induction andchromosome doubling that result in the development of dihaploidcultivars. The breeder can theoretically generate billions of differentgenetic combinations via crossing, selfing and mutations and the same istrue for the utilization of the dihaploid breeding method.

Each year, the plant breeder selects the germplasm to advance to thenext generation. This germplasm is grown under unique and differentgeographical, climatic and soil conditions, and further selections arethen made, during and at the end of the growing season. The cultivarsdeveloped are unpredictable. This unpredictability is because thebreeder's selection occurs in unique environments, with no control atthe DNA level (using conventional breeding procedures or dihaploidbreeding procedures), and with millions of different possible geneticcombinations being generated. A breeder of ordinary skill in the artcannot predict the final resulting cultivars he develops, exceptpossibly in a very gross and general fashion. This unpredictabilityresults in the expenditure of large research monies to develop superiornew bean cultivars.

The development of commercial bean cultivar requires the development andselection of bean plants, the crossing of these plants, and theevaluation of the crosses.

Pedigree breeding and recurrent selection breeding methods are used todevelop cultivars from breeding populations. Breeding programs combinedesirable traits from two or more cultivars or various broad-basedsources into breeding pools from which cultivars are developed byselfing and selection of desired phenotypes or through the dihaploidbreeding method followed by the selection of desired phenotypes. The newcultivars are evaluated to determine which have commercial potential.

Choice of breeding or selection methods depends on the mode of plantreproduction, the heritability of the trait(s) being improved, and thetype of cultivar used commercially (e.g., F hybrid cultivar, purelinecultivar, etc.). For highly heritable traits, a choice of superiorindividual plants evaluated at a single location will be effective,whereas for traits with low heritability, selection should be based onmean values obtained from replicated evaluations of families of relatedplants. Popular selection methods commonly include pedigree selection,modified pedigree selection, mass selection, recurrent selection, andbackcross breeding.

i. Pedigree Selection

Pedigree breeding is used commonly for the improvement ofself-pollinating crops or inbred lines of cross-pollinating crops. Twoparents possessing favorable, complementary traits are crossed toproduce an F₁. An F₂ population is produced by selfing one or severalF₁s or by intercrossing two F₁s (sib mating). The dihaploid breedingmethod could also be used. Selection of the best individuals is usuallybegun in the F₂ population; then, beginning in the F₃, the bestindividuals in the best families are selected. Replicated testing offamilies, or hybrid combinations involving individuals of thesefamilies, often follows in the F₄ generation to improve theeffectiveness of selection for traits with low heritability. At anadvanced stage of inbreeding (i.e., F₆ and F₇), the best lines ormixtures of phenotypically similar lines are tested for potentialrelease of new cultivars. Similarly, the development of new cultivarsthrough the dihaploid system requires the selection of the cultivarsfollowed by two to five years of testing in replicated plots.

The single-seed descent procedure in the strict sense refers to plantinga segregating population, harvesting a sample of one seed per plant, andusing the one-seed sample to plant the next generation. When thepopulation has been advanced from the F2 to the desired level ofinbreeding, the plants from which lines are derived will each trace todifferent F2 individuals. The number of plants in a population declineseach generation due to failure of some seeds to germinate or some plantsto produce at least one seed. As a result, not all of the F2 plantsoriginally sampled in the population will be represented by a progenywhen generation advance is completed.

In a multiple-seed procedure, breeders commonly harvest one or morefruit containing seed from each plant in a population and blend themtogether to form a bulk seed lot. Part of the bulked seed is used toplant the next generation and part is put in reserve. The procedure hasbeen referred to as modified single-seed descent or the bulk technique.

The multiple-seed procedure has been used to save labor at harvest. Itis considerably faster than removing one seed from each fruit by handfor the single seed procedure. The multiple-seed procedure also makes itpossible to plant the same number of seeds of a population eachgeneration of inbreeding. Enough seeds are harvested to make up forthose plants that did not germinate or produce seed.

Descriptions of other breeding methods that are commonly used fordifferent traits and crops can be found in one of several referencebooks (e.g., R. W. Allard, 1960, Principles of Plant Breeding, JohnWiley and Son, pp. 115-161; N. W. Simmonds, 1979, Principles of CropImprovement, Longman Group Limited; W. R. Fehr, 1987, Principles of CropDevelopment, Macmillan Publishing Co.; N. F. Jensen, 1988, PlantBreeding Methodology, John Wiley & Sons).

ii. Backcross Breeding

Backcross breeding has been used to transfer genes for a simplyinherited, highly heritable trait into a desirable homozygous cultivaror inbred line which is the recurrent parent. The source of the trait tobe transferred is called the donor parent. The resulting plant isexpected to have the attributes of the recurrent parent (e.g., cultivar)and the desirable trait transferred from the donor parent. After theinitial cross, individuals possessing the phenotype of the donor parentare selected and repeatedly crossed (backcrossed) to the recurrentparent. The resulting plant is expected to have the attributes of therecurrent parent (e.g., cultivar) and the desirable trait transferredfrom the donor parent.

When the term bean plant is used in the context of the presentdisclosure, this also includes any bean plant where one or more desiredtraits have been introduced through backcrossing methods, whether suchtrait is from a naturally occurring mutation(s), an artificially-inducedmutation(s), a gene or a nucleotide sequence modified by the use of NewBreeding Techniques. Backcrossing methods can be used with the presentdisclosure to improve or introduce one or more characteristic into thebean plant of the present disclosure. The term “backcrossing” as usedherein refers to the repeated crossing of a hybrid progeny back to therecurrent parent, i.e., backcrossing one, two, three, four, five, six,seven, eight, nine, or more times to the recurrent parent. The parentalbean plant which contributes the gene or the genes for the desiredcharacteristic is termed the nonrecurrent or donor parent. Thisterminology refers to the fact that the nonrecurrent parent is used onetime in the backcross protocol and therefore does not recur. Theparental bean plant to which the gene or genes from the nonrecurrentparent are transferred is known as the recurrent parent as it is usedfor several rounds in the backcrossing protocol.

In a typical backcross protocol, the original cultivar of interest(recurrent parent) is crossed to or by a second cultivar (nonrecurrentparent) that carries the gene or genes of interest to be transferred.The resulting progeny from this cross are then crossed again to or bythe recurrent parent and the process is repeated until a bean plant isobtained wherein all of the desired morphological and physiologicalcharacteristics of the recurrent parent are recovered in the convertedplant, generally determined at a 5% significance level when grown in thesame environmental conditions, in addition to the gene or genestransferred from the nonrecurrent parent. It has to be noted that some,one, two, three or more, self-pollination and growing of populationmight be included between two successive backcrosses. Indeed, anappropriate selection in the population produced by theself-pollination, i.e., selection for the desired trait andphysiological and morphological characteristics of the recurrent parentmight be equivalent to one, two or even three additional backcrosses ina continuous series without rigorous selection, saving then time, moneyand effort to the breeder. A non-limiting example of such a protocolwould be the following: a) the first generation F1 produced by the crossof the recurrent parent A by the donor parent B is backcrossed to parentA, b) selection is practiced for the plants having the desired trait ofparent B, c) selected plant are self-pollinated to produce a populationof plants where selection is practiced for the plants having the desiredtrait of parent B and physiological and morphological characteristics ofparent A, d) the selected plants are backcrossed one, two, three, four,five, six, seven, eight, nine, or more times to parent A to produceselected backcross progeny plants comprising the desired trait of parentB and the physiological and morphological characteristics of parent A.Step (c) may or may not be repeated and included between the backcrossesof step (d).

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto alter or substitute one or more trait(s) or characteristic(s) in theoriginal inbred parental line in order to find it then in the hybridmade thereof. To accomplish this, a gene or genes of the recurrentinbred is modified or substituted with the desired gene or genes fromthe nonrecurrent parent, while retaining essentially all of the rest ofthe desired genetic, and therefore the desired physiological andmorphological, constitution of the original inbred. The choice of theparticular nonrecurrent parent will depend on the purpose of thebackcross; one of the major purposes is to add some commerciallydesirable, agronomically important trait(s) to the plant. The exactbackcrossing protocol will depend on the characteristic(s) or trait(s)being altered to determine an appropriate testing protocol. Althoughbackcrossing methods are simplified when the characteristic beingtransferred is a single gene and dominant allele, multiple genes andrecessive allele(s) may also be transferred and therefore, backcrossbreeding is by no means restricted to character(s) governed by one or afew genes. In fact the number of genes might be less important that theidentification of the character(s) in the segregating population. Inthis instance it may then be necessary to introduce a test of theprogeny to determine if the desired characteristic(s) has beensuccessfully transferred. Such tests encompass visual inspection, simplecrossing, but also follow up of the characteristic(s) throughgenetically associated markers and molecular assisted breeding tools.For example, selection of progeny containing the transferred trait isdone by direct selection, visual inspection for a trait associated witha dominant allele, while the selection of progeny for a trait that istransferred via a recessive allele, require selfing the progeny or usingmolecular markers to determine which plant carry the recessiveallele(s).

Many single gene traits have been identified that are not regularlyselected for in the development of a new parental inbred of a hybridbean plant according to the disclosure but that can be improved bybackcrossing techniques. Examples of these traits include but are notlimited to herbicide resistance (such as bar or pat genes), resistancefor bacterial, fungal, or viral disease (such as gene I used for BCMVresistance), insect resistance, enhanced nutritional quality (such as 2salbumin gene), industrial usage, agronomic qualities (such as the“persistent green gene”), yield stability, and yield enhancement. Manysingle gene traits have been identified that are not regularly selectedfor in the development of a new line but that can be improved bybackcrossing techniques. These genes are generally inherited through thenucleus. Some other single gene traits are described in U.S. Pat. Nos.5,777,196, 5,948,957, and 5,969,212, the disclosures of which arespecifically hereby incorporated by reference.

The backcross breeding method provides a precise way of improvingvarieties that excel in a large number of attributes but are deficientin a few characteristics. (Page 150 of the Pr. R. W. Allard's 1960 book,published by John Wiley & Sons, Inc, Principles of Plant Breeding). Themethod makes use of a series of backcrosses to the variety to beimproved during which the character or the characters in whichimprovement is sought is maintained by selection. At the end of thebackcrossing the gene or genes being transferred unlike all other genes,will be heterozygous. Selfing after the last backcross produceshomozygosity for this gene pair(s) and, coupled with selection, willresult in a parental line of a hybrid variety with exactly oressentially the same adaptation, yielding ability and qualitycharacteristics of the recurrent parent but superior to that parent inthe particular characteristic(s) for which the improvement program wasundertaken. Therefore, this method provides the plant breeder with ahigh degree of genetic control of his work.

The method is scientifically exact because the morphological andagricultural features of the improved variety could be described inadvance and because the same variety could, if it were desired, be breda second time by retracing the same steps (Briggs, “Breeding wheatsresistant to bunt by the backcross method”, 1930 Jour. Amer. Soc.Agron., 22: 289-244).

Backcrossing is a powerful mechanism for achieving homozygosity and anypopulation obtained by backcrossing must rapidly converge on thegenotype of the recurrent parent. When backcrossing is made the basis ofa plant breeding program, the genotype of the recurrent parent will bemodified only with regards to genes being transferred, which aremaintained in the population by selection.

Successful backcrosses are, for example, the transfer of stem rustresistance from ‘Hope’ wheat to ‘Bart wheat’ and even pursuing thebackcrosses with the transfer of bunt resistance to create ‘Bart 38’,having both resistances. Also highlighted by Allard is the successfultransfer of mildew, leaf spot and wilt resistances in California Commonalfalfa to create ‘Caliverde’. This new ‘Caliverde’ variety producedthrough the backcross process is indistinguishable from CaliforniaCommon except for its resistance to the three named diseases.

One of the advantages of the backcross method is that the breedingprogram can be carried out in almost every environment that will allowthe development of the character being transferred.

The backcross technique is not only desirable when breeding for diseaseresistance but also for the adjustment of morphological characters,colour characteristics and simply inherited quantitative characters suchas earliness, plant height and seed size and shape.

iii. Open-Pollinated Populations

The improvement of open-pollinated populations of such crops as rye,maize, sugar beets, herbage grasses, legumes such as alfalfa and clover,and tropical tree crops such as cacao, coconuts, oil palm and somerubber, depends essentially upon changing gene-frequencies towardsfixation of favorable alleles while maintaining a high (but far frommaximal) degree of heterozygosity.

Uniformity in such populations is impossible and trueness-to-type in anopen-pollinated variety is a statistical feature of the population as awhole, not a characteristic of individual plants. Thus, theheterogeneity of open-pollinated populations contrasts with thehomogeneity (or virtually so) of inbred lines, clones and hybrids.

Population improvement methods fall naturally into two groups, thosebased on purely phenotypic selection, normally called mass selection,and those based on selection with progeny testing. Interpopulationimprovement utilizes the concept of open breeding populations; allowinggenes to flow from one population to another. Plants in one population(cultivar, strain, ecotype, or any germplasm source) are crossed eithernaturally (e.g., by wind) or by hand or by bees (commonly Apis melliferaL. or Megachile rotundata F.) with plants from other populations.Selection is applied to improve one (or sometimes both) population(s) byisolating plants with desirable traits from both sources.

There are basically two primary methods of open-pollinated populationimprovement.

First, there is the situation in which a population is changed en masseby a chosen selection procedure. The outcome is an improved populationthat is indefinitely propagable by random-mating within itself inisolation.

Second, the synthetic variety attains the same end result as populationimprovement, but is not itself propagable as such; it has to bereconstructed from parental lines or clones. These plant breedingprocedures for improving open-pollinated populations are well known tothose skilled in the art and comprehensive reviews of breedingprocedures routinely used for improving cross-pollinated plants areprovided in numerous texts and articles, including: Allard, Principlesof Plant Breeding, John Wiley & Sons, Inc. (1960); Simmonds, Principlesof Crop Improvement, Longman Group Limited (1979); Hallauer and Miranda,Quantitative Genetics in Maize Breeding, Iowa State University Press(1981); and, Jensen, Plant Breeding Methodology, John Wiley & Sons, Inc.(1988).

A) Mass Selection

Mass and recurrent selections can be used to improve populations ofeither self- or cross-pollinating crops. A genetically variablepopulation of heterozygous individuals is either identified or createdby intercrossing several different parents. The best plants are selectedbased on individual superiority, outstanding progeny, or excellentcombining ability. The selected plants are intercrossed to produce a newpopulation in which further cycles of selection are continued. In massselection, desirable individual plants are chosen, harvested, and theseed composited without progeny testing to produce the followinggeneration. Since selection is based on the maternal parent only, andthere is no control over pollination, mass selection amounts to a formof random mating with selection. As stated above, the purpose of massselection is to increase the proportion of superior genotypes in thepopulation.

B) Synthetics

A synthetic variety is produced by crossing inter se a number ofgenotypes selected for good combining ability in all possible hybridcombinations, with subsequent maintenance of the variety by openpollination. Whether parents are (more or less inbred) seed-propagatedlines, as in some sugar beet and beans (Vicia) or clones, as in herbagegrasses, clovers and alfalfa, makes no difference in principle. Parentsare selected on general combining ability, sometimes by test crosses ortopcrosses, more generally by polycrosses. Parental seed lines may bedeliberately inbred (e.g. by selfing or sib crossing). However, even ifthe parents are not deliberately inbred, selection within lines duringline maintenance will ensure that some inbreeding occurs. Clonal parentswill, of course, remain unchanged and highly heterozygous.

Whether a synthetic can go straight from the parental seed productionplot to the farmer or must first undergo one or more cycles ofmultiplication depends on seed production and the scale of demand forseed. In practice, grasses and clovers are generally multiplied once ortwice and are thus considerably removed from the original synthetic.

While mass selection is sometimes used, progeny testing is generallypreferred for polycrosses, because of their operational simplicity andobvious relevance to the objective, namely exploitation of generalcombining ability in a synthetic.

The number of parental lines or clones that enters a synthetic varieswidely. In practice, numbers of parental lines range from 10 to severalhundred, with 100-200 being the average. Broad based synthetics formedfrom 100 or more clones would be expected to be more stable during seedmultiplication than narrow based synthetics.

iv. Hybrids

A hybrid is an individual plant resulting from a cross between parentsof differing genotypes. Commercial hybrids are now used extensively inmany crops, including corn (maize), sorghum, sugar beet, sunflowerbroccoli, and bean. Hybrids can be formed in a number of different ways,including by crossing two parents directly (single cross hybrids), bycrossing a single cross hybrid with another parent (three-way or triplecross hybrids), or by crossing two different hybrids (four-way or doublecross hybrids).

Strictly speaking, most individuals in an out breeding (i.e.,open-pollinated) population are hybrids, but the term is usuallyreserved for cases in which the parents are individuals whose genomesare sufficiently distinct for them to be recognized as different speciesor subspecies. Hybrids may be fertile or sterile depending onqualitative and/or quantitative differences in the genomes of the twoparents. Heterosis, or hybrid vigor, is usually associated withincreased heterozygosity that results in increased vigor of growth,survival, and fertility of hybrids as compared with the parental linesthat were used to form the hybrid. Maximum heterosis is usually achievedby crossing two genetically different, highly inbred lines.

Once the inbreds that give the best hybrid performance have beenidentified, the hybrid seed can be reproduced indefinitely as long asthe homogeneity of the inbred parent is maintained. A single-crosshybrid is produced when two inbred lines are crossed to produce the F1progeny. A double-cross hybrid is produced from four inbred linescrossed in pairs (A×B and C×D) and then the two F1 hybrids are crossedagain (A×B)×(C×D). Much of the hybrid vigor and uniformity exhibited byF1 hybrids is lost in the next generation (F2). Consequently, seed fromF2 hybrid varieties is not used for planting stock.

The production of hybrids is a well-developed industry, involving theisolated production of both the parental lines and the hybrids whichresult from crossing those lines. For a detailed discussion of thehybrid production process, see, e.g., Wright, Commercial Hybrid SeedProduction 8:161-176, In Hybridization of Crop Plants.

v. Bulk Segregation Analysis (BSA)

BSA, a.k.a. bulked segregation analysis, or bulk segregant analysis, isa method described by Michelmore et al. (Michelmore et al., 1991,Identification of markers linked to disease-resistance genes by bulkedsegregant analysis: a rapid method to detect markers in specific genomicregions by using segregating populations. Proceedings of the NationalAcademy of Sciences, USA, 99:9828-9832) and Quarrie et al. (Quarrie etal., 1999, Journal of Experimental Botany, 50(337):1299-1306).

For BSA of a trait of interest, parental lines with certain differentphenotypes are chosen and crossed to generate F2, doubled haploid orrecombinant inbred populations with QTL analysis. The population is thenphenotyped to identify individual plants or lines having high or lowexpression of the trait. Two DNA bulks are prepared, one from theindividuals having one phenotype (e.g., resistant to virus), and theother from the individuals having reversed phenotype (e.g., susceptibleto virus), and analyzed for allele frequency with molecular markers.Only a few individuals are required in each bulk (e.g., 10 plants each)if the markers are dominant (e.g., RAPDs). More individuals are neededwhen markers are co-dominant (e.g., RFLPs, SNPs or SSRs). Markers linkedto the phenotype can be identified and used for breeding or QTL mapping.

vi. Hand-Pollination Method

Hand pollination describes the crossing of plants via the deliberatefertilization of female ovules with pollen from a desired male parentplant. In some embodiments the donor or recipient female parent and thedonor or recipient male parent line are planted in the same field. Insome embodiments the donor or recipient female parent and the donor orrecipient male parent line are planted in the same greenhouse. Theinbred male parent can be planted earlier than the female parent toensure adequate pollen supply at the pollination time. In someembodiments, the male parent and female parent can be planted at a ratioof 1 male parent to 4-10 female parents. Pollination is started when thefemale parent flower is ready to be fertilized. Female flower buds thatare ready to open in the following days are identified, covered withpaper cups or small paper bags that prevent bee or any other insect fromvisiting the female flowers, and marked with any kind of material thatcan be easily seen the next morning. The male flowers of the male parentare collected in the early morning before they are open and visited bypollinating insects. The covered female flowers of the female parent,which have opened, are un-covered and pollinated with the collectedfresh male flowers of the male parent, starting as soon as the maleflower sheds pollen. The pollinated female flowers are again coveredafter pollination to prevent bees and any other insects visit. Thepollinated female flowers are also marked. The marked flowers areharvested. In some embodiments, the male pollen used for fertilizationhas been previously collected and stored.

vii. Bee-Pollination Method

Using the bee-pollination method, the parent plants are usually plantedwithin close proximity. In some embodiments more female plants areplanted to allow for a greater production of seed. Insects are placed inthe field or greenhouses for transfer of pollen from the male parent tothe female flowers of the female parent.

viii. Targeting Induced Local Lesions in Genomes (TILLING)

Breeding schemes of the present application can include crosses withTILLING® plant cultivars. TILLING® is a method in molecular biology thatallows directed identification of mutations in a specific gene. TILLING®was introduced in 2000, using the model plant Arabidopsis thaliana.TILLING® has since been used as a reverse genetics method in otherorganisms such as zebrafish, corn, wheat, rice, soybean, bean, tomatoand lettuce.

The method combines a standard and efficient technique of mutagenesiswith a chemical mutagen (e.g., Ethyl methanesulfonate (EMS)) with asensitive DNA screening-technique that identifies single base mutations(also called point mutations) in a target gene. EcoTILLING is a methodthat uses TILLING® techniques to look for natural mutations inindividuals, usually for population genetics analysis (see Comai, etal., 2003 The Plant Journal 37, 778-786; Gilchrist et al. 2006 Mol.Ecol. 15, 1367-1378; Mejlhede et al. 2006 Plant Breeding 125, 461-467;Nieto et al. 2007 BMC Plant Biology 7, 34-42, each of which isincorporated by reference hereby for all purposes). DEcoTILLING is amodification of TILLING® and EcoTILLING which uses an inexpensive methodto identify fragments (Garvin et al., 2007, DEco-TILLING: An inexpensivemethod for SNP discovery that reduces ascertainment bias. MolecularEcology Notes 7, 735-746).

The TILLING® method relies on the formation of heteroduplexes that areformed when multiple alleles (which could be from a heterozygote or apool of multiple homozygotes and heterozygotes) are amplified in a PCR,heated, and then slowly cooled. A “bubble” forms at the mismatch of thetwo DNA strands (the induced mutation in TILLING® or the naturalmutation or SNP in EcoTILLING), which is then cleaved by single strandednucleases. The products are then separated by size on several differentplatforms.

Several TILLING® centers exists over the world that focus onagriculturally important species: UC Davis (USA), focusing on Rice;Purdue University (USA), focusing on Maize; University of BritishColumbia (CA), focusing on Brassica napus; John Innes Centre (UK),focusing on Brassica rapa; Fred Hutchinson Cancer Research, focusing onArabidopsis; Southern Illinois University (USA), focusing on Soybean;John Innes Centre (UK), focusing on Lotus and Medicago; and INRA(France), focusing on Pea and Tomato.

More detailed description on methods and compositions on TILLING® can befound in U.S. Pat. No. 5,994,075, US 2004/0053236 A1, WO 2005/055704,and WO 2005/048692, each of which is hereby incorporated by referencefor all purposes.

Thus, in some embodiments, the breeding methods of the presentdisclosure include breeding with one or more TILLING plant lines withone or more identified mutations.

ix. Mutation Breeding

Mutation breeding is another method of introducing new traits into beanplants. Mutations that occur spontaneously or are artificially inducedcan be useful sources of variability for a plant breeder. The goal ofartificial mutagenesis is to increase the rate of mutation for a desiredcharacteristic. Mutation rates can be increased by many different meansor mutating agents including temperature, long-term seed storage, tissueculture conditions, radiation (such as X-rays, Gamma rays, neutrons,Beta radiation, or ultraviolet radiation), chemical mutagens (such asbase analogs like 5-bromo-uracil), antibiotics, alkylating agents (suchas sulfur mustards, nitrogen mustards, epoxides, ethyleneamines,sulfates, sulfonates, sulfones, or lactones), azide, hydroxylamine,nitrous acid or acridines. Once a desired trait is observed throughmutagenesis the trait may then be incorporated into existing germplasmby traditional breeding techniques. Details of mutation breeding can befound in W. R. Fehr, 1993, Principles of Cultivar Development, MacmillanPublishing Co.

New breeding techniques such as the ones involving the uses ofengineered nuclease to enhance the efficacy and precision of geneediting in combination with oligonucleotides including, but not limitedto Zinc Finger Nucleases (ZFN), TAL effector nucleases (TALEN5) andclustered regularly interspaced short palindromic repeats(CRISPR)-associated endonuclease Cas9 (CRISPR-Cas9) using such as Cas9,Cas12a/Cpf1, Cas13/C2c2, CasX and CasY or oligonucleotide directedmutagenesis shall also be used to generate genetic variability andintroduce new traits into bean varieties.

x. Double Haploids and Chromosome Doubling

One way to obtain homozygous plants without the need to cross twoparental lines followed by a long selection of the segregating progeny,and/or multiple back-crossings is to produce haploids and then doublethe chromosomes to form doubled haploids. Haploid plants can occurspontaneously, or may be artificially induced via chemical treatments orby crossing plants with inducer lines (Seymour et al. 2012, PNAS vol109, pg 4227-4232; Zhang et al., 2008 Plant Cell Rep. December 27(12)1851-60). The production of haploid progeny can occur via a variety ofmechanisms which can affect the distribution of chromosomes duringgamete formation. The chromosome complements of haploids sometimesdouble spontaneously to produce homozygous doubled haploids (DHs).Mixoploids, which are plants which contain cells having differentploidies, can sometimes arise and may represent plants that areundergoing chromosome doubling so as to spontaneously produce doubledhaploid tissues, organs, shoots, floral parts or plants. Another commontechnique is to induce the formation of double haploid plants with achromosome doubling treatment such as colchicine (El-Hennawy et al.,2011 Vol 56, issue 2 pg 63-72; Doubled Haploid Production in Crop Plants2003 edited by Maluszynski ISBN 1-4020-1544-5). The production ofdoubled haploid plants yields highly uniform cultivars and is especiallydesirable as an alternative to sexual inbreeding of longer-generationcrops. By producing doubled haploid progeny, the number of possible genecombinations for inherited traits is more manageable. Thus, an efficientdoubled haploid technology can significantly reduce the time and thecost of inbred and cultivar development.

xi. Protoplast Fusion

In another method for breeding plants, protoplast fusion can also beused for the transfer of trait-conferring genomic material from a donorplant to a recipient plant. Protoplast fusion is an induced orspontaneous union, such as a somatic hybridization, between two or moreprotoplasts (cells of which the cell walls are removed by enzymatictreatment) to produce a single bi- or multi-nucleate cell. The fusedcell that may even be obtained with plant species that cannot beinterbred in nature is tissue cultured into a hybrid plant exhibitingthe desirable combination of traits.

xii. Embryo Rescue

Alternatively, embryo rescue may be employed in the transfer ofresistance-conferring genomic material from a donor plant to a recipientplant. Embryo rescue can be used as a procedure to isolate embryo's fromcrosses wherein plants fail to produce viable seed. In this process, thefertilized ovary or immature seed of a plant is tissue cultured tocreate new plants (see Pierik, 1999, In vitro culture of higher plants,Springer, ISBN 079235267x, 9780792352679, which is incorporated hereinby reference in its entirety).

xiii. Gene Editing/Genome Editing

Gene editing (or Genome editing) technologies. Breeding and selectionschemes of the present disclosure can include crosses with plant linesthat have undergone genome editing. In some embodiments, the breedingand selection methods of the present disclosure are compatible withplants that have been modified using any gene and/or genome editingtool, including, but not limited to: ZFNs, TALENS, CRISPR, and Meganuclease technologies. In some embodiments, persons having skill in theart will recognize that the breeding methods of the present disclosureare compatible with many other gene editing technologies. In someembodiments, the present disclosure teaches gene-editing technologiescan be applied for a single locus conversion, for example, conferringbean plant with herbicide resistance. In some embodiments, the presentdisclosure teaches that the single locus conversion is an artificiallymutated gene or nucleotide sequence that has been modified through theuse of breeding techniques taught herein.

In some embodiments, the breeding and selection methods of the presentdisclosure are compatible with plants that have been modified throughZinc Finger Nucleases. Three variants of the ZFN technology arerecognized in plant breeding (with applications ranging from producingsingle mutations or short deletions/insertions in the case of ZFN-1 and-2 techniques up to targeted introduction of new genes in the case ofthe ZFN-3 technique); 1) ZFN-1: Genes encoding ZFNs are delivered toplant cells without a repair template. The ZFNs bind to the plant DNAand generate site specific double-strand breaks (DSBs). The naturalDNA-repair process (which occurs through nonhomologous end-joining,NHEJ) leads to site specific mutations, in one or only a few base pairs,or to short deletions or insertions; 2) ZFN-2: Genes encoding ZFNs aredelivered to plant cells along with a repair template homologous to thetargeted area, spanning a few kilo base pairs. The ZFNs bind to theplant DNA and generate site-specific DSBs. Natural gene repairmechanisms generate site-specific point mutations e.g. changes to one ora few base pairs through homologous recombination and the copying of therepair template; and 3) ZFN-3: Genes encoding ZFNs are delivered toplant cells along with a stretch of DNA which can be several kilo basepairs long and the ends of which are homologous to the DNA sequencesflanking the cleavage site. As a result, the DNA stretch is insertedinto the plant genome in a site-specific manner.

In some embodiments, the breeding and selection methods of the presentdisclosure are compatible with plants that have been modified throughTranscription activator-like (TAL) effector nucleases (TALEN5). TALENSare polypeptides with repeat polypeptide arms capable of recognizing andbinding to specific nucleic acid regions. By engineering the polypeptidearms to recognize selected target sequences, the TAL nucleases can beused to direct double stranded DNA breaks to specific genomic regions.These breaks can then be repaired via recombination to edit, delete,insert, or otherwise modify the DNA of a host organism. In someembodiments, TALENSs are used alone for gene editing (e.g., for thedeletion or disruption of a gene). In other embodiments, TALs are usedin conjunction with donor sequences and/or other recombination factorproteins that will assist in the Non-homologous end joining (NHEJ)process to replace the targeted DNA region. For more information on theTAL-mediated gene editing compositions and methods of the presentdisclosure, see U.S. Pat. Nos. 8,440,432; 8,450,471; 8,586,526;8,586,363; 8,592,645; 8,697,853; 8,704,041; 8,921,112; and 8,912,138,each of which is hereby incorporated in its entirety for all purposes.

In some embodiments, the breeding and selection methods of the presentdisclosure are compatible with plants that have been modified throughClustered Regularly Interspaced Short Palindromic Repeats (CRISPR) orCRISPR-associated (Cas) gene editing tools. CRISPR proteins wereoriginally discovered as bacterial adaptive immunity systems whichprotected bacteria against viral and plasmid invasion. There are atleast three main CRISPR system types (Type I, II, and III) and at least10 distinct subtypes (Makarova, K. S., et. al., Nat Rev Microbiol. 2011May 9; 9(6):467-477). Type I and III systems use Cas protein complexesand short guide polynucleotide sequences to target selected DNA regions.Type II systems rely on a single protein (e.g. Cas9) and the targetingguide polynucleotide, where a portion of the 5′ end of a guide sequenceis complementary to a target nucleic acid. For more information on theCRISPR gene editing compositions and methods of the present disclosure,see U.S. Pat. Nos. 8,697,359; 8,889,418; 8,771,945; and 8,871,445, eachof which is hereby incorporated in its entirety for all purposes.

In some embodiments, the breeding and selection methods of the presentdisclosure are compatible with plants that have been modified throughmeganucleases. In some embodiments, meganucleases are engineeredendonucleases capable of targeting selected DNA sequences and inducingDNA breaks. In some embodiments, new meganucleases targeting specificregions are developed through recombinant techniques which combine theDNA binding motifs from various other identified nucleases. In otherembodiments, new meganucleases are created through semi-rationalmutational analysis, which attempts to modify the structure of existingbinding domains to obtain specificity for additional sequences. For moreinformation on the use of meganucleases for genome editing, see Silva etal., 2011 Current Gene Therapy 11 pg 11-27; and Stoddard et al., 2014Mobile DNA 5 pg 7, each of which is hereby incorporated in its entiretyfor all purposes.

Plant Transformation

Bean plants of the present disclosure, such as ‘HMX0175722’ can befurther modified by introducing one or more transgenes which whenexpressed lead to desired phenotypes. The most common method for theintroduction of new genetic material into a plant genome involves theuse of living cells of the bacterial pathogen Agrobacterium tumefaciensto literally inject a piece of DNA, called transfer or T-DNA, intoindividual plant cells (usually following wounding of the tissue) whereit is targeted to the plant nucleus for chromosomal integration. Thereare numerous patents governing Agrobacterium mediated transformation andparticular DNA delivery plasmids designed specifically for use withAgrobacterium—for example, U.S. Pat. No. 4,536,475, EP0265556,EP0270822, WO8504899, WO8603516, U.S. Pat. No. 5,591,616, EP0604662,EP0672752, WO8603776, WO9209696, WO9419930, WO9967357, U.S. Pat. No.4,399,216, WO8303259, U.S. Pat. No. 5,731,179, EP068730, WO9516031, U.S.Pat. Nos. 5,693,512, 6,051,757 and EP904362A1. Agrobacterium-mediatedplant transformation involves as a first step the placement of DNAfragments cloned on plasmids into living Agrobacterium cells, which arethen subsequently used for transformation into individual plant cells.Agrobacterium-mediated plant transformation is thus an indirect planttransformation method. Methods of Agrobacterium-mediated planttransformation that involve using vectors with no T-DNA are also wellknown to those skilled in the art and can have applicability in thepresent disclosure. See, for example, U.S. Pat. No. 7,250,554, whichutilizes P-DNA instead of T-DNA in the transformation vector.

Direct plant transformation methods using DNA have also been reported.The first of these to be reported historically is electroporation, whichutilizes an electrical current applied to a solution containing plantcells (M. E. Fromm et al., Nature, 319, 791 (1986); H. Jones et al.,Plant Mol. Biol., 13, 501 (1989) and H. Yang et al., Plant Cell Reports,7, 421 (1988). Another direct method, called “biolistic bombardment”,uses ultrafine particles, usually tungsten or gold, that are coated withDNA and then sprayed onto the surface of a plant tissue with sufficientforce to cause the particles to penetrate plant cells, including thethick cell wall, membrane and nuclear envelope, but without killing atleast some of them (U.S. Pat. Nos. 5,204,253, 5,015,580). A third directmethod uses fibrous forms of metal or ceramic consisting of sharp,porous or hollow needle-like projections that literally impale thecells, and also the nuclear envelope of cells. Both silicon carbide andaluminum borate whiskers have been used for plant transformation (Mizunoet al., 2004; Petolino et al., 2000; U.S. Pat. No. 5,302,523 USApplication 20040197909) and also for bacterial and animaltransformation (Kaepler et al., 1992; Raloff, 1990; Wang, 1995). Thereare other methods reported, and undoubtedly, additional methods will bedeveloped. However, the efficiencies of each of these indirect or directmethods in introducing foreign DNA into plant cells are invariablyextremely low, making it necessary to use some method for selection ofonly those cells that have been transformed, and further, allowinggrowth and regeneration into plants of only those cells that have beentransformed.

For efficient plant transformation, a selection method must be employedsuch that whole plants are regenerated from a single transformed celland every cell of the transformed plant carries the DNA of interest.These methods can employ positive selection, whereby a foreign gene issupplied to a plant cell that allows it to utilize a substrate presentin the medium that it otherwise could not use, such as mannose or xylose(for example, refer U.S. Pat. Nos. 5,767,378; 5,994,629). Moretypically, however, negative selection is used because it is moreefficient, utilizing selective agents such as herbicides or antibioticsthat either kill or inhibit the growth of nontransformed plant cells andreducing the possibility of chimeras. Resistance genes that areeffective against negative selective agents are provided on theintroduced foreign DNA used for the plant transformation. For example,one of the most popular selective agents used is the antibiotickanamycin, together with the resistance gene neomycin phosphotransferase(nptII), which confers resistance to kanamycin and related antibiotics(see, for example, Messing & Vierra, Gene 19: 259-268 (1982); Bevan etal., Nature 304:184-187 (1983)). However, many different antibiotics andantibiotic resistance genes can be used for transformation purposes(U.S. Pat. Nos. 5,034,322, 6,174,724 and 6,255,560). In addition,several herbicides and herbicide resistance genes have been used fortransformation purposes, including the bar gene, which confersresistance to the herbicide phosphinothricin (White et al., Nucl AcidsRes 18: 1062 (1990), Spencer et al., Theor Appl Genet 79: 625-631(1990),U.S. Pat. Nos. 4,795,855, 5,378,824 and 6,107,549). In addition, thedhfr gene, which confers resistance to the anticancer agentmethotrexate, has been used for selection (Bourouis et al., EMBO J.2(7): 1099-1104 (1983).

Genes can be introduced in a site directed fashion using homologousrecombination. Homologous recombination permits site specificmodifications in endogenous genes and thus inherited or acquiredmutations may be corrected, and/or novel alterations may be engineeredinto the genome. Homologous recombination and site-directed integrationin plants are discussed in, for example, U.S. Pat. Nos. 5,451,513,5,501,967 and 5,527,695.

Methods of producing transgenic plants are well known to those ofordinary skill in the art. Transgenic plants can now be produced by avariety of different transformation methods including, but not limitedto, electroporation; microinjection; microprojectile bombardment, alsoknown as particle acceleration or biolistic bombardment; viral-mediatedtransformation; and Agrobacterium-mediated transformation. See, forexample, U.S. Pat. Nos. 5,405,765; 5,472,869; 5,538,877; 5,538,880;5,550,318; 5,641,664; and 5,736,369; and International PatentApplication Publication Nos. WO/2002/038779 and WO/2009/117555; Lu etal., (Plant Cell Reports, 2008, 27:273-278); Watson et al., RecombinantDNA, Scientific American Books (1992); Hinchee et al., Bio/Tech.6:915-922 (1988); McCabe et al., Bio/Tech. 6:923-926 (1988); Toriyama etal., Bio/Tech. 6:1072-1074 (1988); Fromm et al., Bio/Tech. 8:833-839(1990); Mullins et al., Bio/Tech. 8:833-839 (1990); Hiei et al., PlantMolecular Biology 35:205-218 (1997); Ishida et al., Nature Biotechnology14:745-750 (1996); Zhang et al., Molecular Biotechnology 8:223-231(1997); Ku et al., Nature Biotechnology 17:76-80 (1999); and, Raineri etal., Bio/Tech. 8:33-38 (1990)), each of which is expressly incorporatedherein by reference in their entirety.

Microprojectile bombardment is also known as particle acceleration,biolistic bombardment, and the gene gun (Biolistic® Gene Gun). The genegun is used to shoot pellets that are coated with genes (e.g., fordesired traits) into plant seeds or plant tissues in order to get theplant cells to then express the new genes. The gene gun uses an actualexplosive (.22 caliber blank) to propel the material. Compressed air orsteam may also be used as the propellant. The Biolistic® Gene Gun wasinvented in 1983-1984 at Cornell University by John Sanford, EdwardWolf, and Nelson Allen. It and its registered trademark are now owned byE. I. du Pont de Nemours and Company. Most species of plants have beentransformed using this method.

Agrobacterium tumefaciens is a naturally occurring bacterium that iscapable of inserting its DNA (genetic information) into plants,resulting in a type of injury to the plant known as crown gall. Mostspecies of plants can now be transformed using this method, includingcucurbitaceous species. A transgenic plant formed using Agrobacteriumtransformation methods typically contains a single gene on onechromosome, although multiple copies are possible. Such transgenicplants can be referred to as being hemizygous for the added gene. A moreaccurate name for such a plant is an independent segregant, because eachtransformed plant represents a unique T-DNA integration event (U.S. Pat.No. 6,156,953). A transgene locus is generally characterized by thepresence and/or absence of the transgene. A heterozygous genotype inwhich one allele corresponds to the absence of the transgene is alsodesignated hemizygous (U.S. Pat. No. 6,008,437).

General transformation methods, and specific methods for transformingcertain plant species (e.g., bean) are described in U.S. PatentPublication No. US20190211347 which is incorporated herein by referencein its entirety for all purposes.

Grafting

Grafting is a process that has been used for many years in crops. Butgrafting can be a tool in common bean breeding (Gurusamy et al. Can. J.Plant Sci. 90:299-304, 2010), which teaches that grafting shoots ofdifferent Phaseolus breeding materials onto compatible rootstocks cansuccessfully be used as a tool in bean breeding programs. Grafting maybe used to provide a certain level of resistance to telluric pathogenssuch as Phytophthora or to certain nematodes. Grafting is thereforeintended to prevent contact between the plant or variety to becultivated and the infested soil. The variety of interest used as thegraft or scion, optionally an F i hybrid, is grafted onto the resistantplant used as the rootstock. The resistant rootstock remains healthy andprovides, from the soils, the normal supply for the graft that itisolates from the diseases. In some recent developments, it has alsobeen shown that some rootstocks are also able to improve the agronomicvalue for the grafted plant and in particular the equilibrium betweenthe vegetative and generative development that are always difficult tobalance in bean cultivation.

Breeding Evaluation

Each breeding program can include a periodic, objective evaluation ofthe efficiency of the breeding procedure. Evaluation criteria varydepending on the goal and objectives, but should include gain fromselection per year based on comparisons to an appropriate standard,overall value of the advanced breeding lines, and number of successfulcultivars produced per unit of input (e.g., per year, per dollarexpended, etc.).

Promising advanced breeding lines are thoroughly tested per se and inhybrid combination and compared to appropriate standards in environmentsrepresentative of the commercial target area(s). The best lines arecandidates for use as parents in new commercial cultivars; those stilldeficient in a few traits may be used as parents to produce newpopulations for further selection or in a backcross program to improvethe parent lines for a specific trait.

In one embodiment, the plants are selected on the basis of one or morephenotypic traits. Skilled persons will readily appreciate that suchtraits include any observable characteristic of the plant, including forexample growth rate, vigor, plant health, maturity, branching, height,weight, total yield, color, taste, aroma, changes in the production ofone or more compounds by the plant (including for example, metabolites,proteins, drugs, carbohydrates, oils, and any other compounds).

A most difficult task is the identification of individuals that aregenetically superior, because for most traits the true genotypic valueis masked by other confounding plant traits or environmental factors.One method of identifying a superior plant is to observe its performancerelative to other experimental plants and to a widely grown standardcultivar. If a single observation is inconclusive, replicatedobservations provide a better estimate of its genetic worth.

Proper testing should detect any major faults and establish the level ofsuperiority or improvement over current cultivars. In addition toshowing superior performance, there must be a demand for a new cultivarthat is compatible with industry standards or which creates a newmarket. The introduction of a new cultivar will incur additional coststo the seed producer, the grower, processor and consumer; for specialadvertising and marketing, altered seed and commercial productionpractices, and new product utilization. The testing preceding release ofa new cultivar should take into consideration research and developmentcosts as well as technical superiority of the final cultivar. Forseed-propagated cultivars, it must be feasible to produce seed easilyand economically.

It should be appreciated that in certain embodiments, plants may beselected based on the absence, suppression or inhibition of a certainfeature or trait (such as an undesirable feature or trait) as opposed tothe presence of a certain feature or trait (such as a desirable featureor trait).

Selecting plants based on genotypic information is also envisaged (forexample, including the pattern of plant gene expression, genotype, orpresence of genetic markers). Where the presence of one or more geneticmarker is assessed, the one or more marker may already be known and/orassociated with a particular characteristic of a plant; for example, amarker or markers may be associated with an increased growth rate ormetabolite profile. This information could be used in combination withassessment based on other characteristics in a method of the disclosureto select for a combination of different plant characteristics that maybe desirable. Such techniques may be used to identify novel quantitativetrait loci (QTLs). By way of example, plants may be selected based ongrowth rate, size (including but not limited to weight, height, leafsize, stem size, branching pattern, or the size of any part of theplant), general health, survival, tolerance to adverse physicalenvironments and/or any other characteristic, as described hereinbefore.

Further non-limiting examples include selecting plants based on: speedof seed germination; quantity of biomass produced; increased root,and/or leaf/shoot growth that leads to an increased yield (pods and/orbeans) or biomass production; effects on plant growth that results in anincreased seed yield for a crop; effects on plant growth which result inan increased pod yield; effects on plant growth that lead to anincreased resistance or tolerance to disease including fungal, viral orbacterial diseases or to pests such as insects, mites or nematodes inwhich damage is measured by decreased foliar symptoms such as theincidence of bacterial or fungal lesions, or area of damaged foliage orreduction in the numbers of nematode cysts or galls on plant roots, orimprovements in plant yield in the presence of such plant pests anddiseases; effects on plant growth that lead to increased metaboliteyields; effects on plant growth that lead to improved aesthetic appealwhich may be particularly important in plants grown for their form,color or taste, for example the color intensity of bean leaves, or thetaste of said leaves.

Molecular Breeding Evaluation Techniques

Selection of plants based on phenotypic or genotypic information may beperformed using techniques such as, but not limited to: high through-putscreening of chemical components of plant origin, sequencing techniquesincluding high through-put sequencing of genetic material, differentialdisplay techniques (including DDRT-PCR, and DD-PCR), nucleic acidmicroarray techniques, RNA-seq (Whole Transcriptome Shotgun Sequencing),qRTPCR (quantitative real time PCR).

In one embodiment, the evaluating step of a plant breeding programinvolves the identification of desirable traits in progeny plants.Progeny plants can be grown in, or exposed to conditions designed toemphasize a particular trait (e.g. drought conditions for droughttolerance, lower temperatures for freezing tolerant traits). Progenyplants with the highest scores for a particular trait may be used forsubsequent breeding steps.

In some embodiments, plants selected from the evaluation step canexhibit a 1%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%,65%, 70%, 75%, 80%, 85%, 90%, 95%, 100%, 120% or more improvement in aparticular plant trait compared to a control plant.

In other embodiments, the evaluating step of plant breeding comprisesone or more molecular biological tests for genes or other markers. Forexample, the molecular biological test can involve probe hybridizationand/or amplification of nucleic acid (e.g., measuring nucleic aciddensity by Northern or Southern hybridization, PCR) and/or immunologicaldetection (e.g., measuring protein density, such as precipitation andagglutination tests, ELISA (e.g., Lateral Flow test or DAS-ELISA),Western blot, Radioimmune Assay (RIA), immune labeling, immunosorbentelectron microscopy (ISEM), and/or dot blot).

The procedure to perform a nucleic acid hybridization, an amplificationof nucleic acid (e.g., PCT, RT-PCR) or an immunological detection (e.g.,precipitation and agglutination tests, ELISA (e.g., Lateral Flow test orDAS-ELISA), Western blot, RIA, immunogold or immunofluorescent labeling,immunosorbent electron microscopy (ISEM), and/or dot blot tests) areperformed as described elsewhere herein and well-known by one skilled inthe art.

In one embodiment, the evaluating step comprises PCR (semi-quantitativeor quantitative), wherein primers are used to amplify one or morenucleic acid sequences of a desirable gene, or a nucleic acid associatedwith said gene or a desirable trait (e.g., a co-segregating nucleicacid, or other marker).

In another embodiment, the evaluating step comprises immunologicaldetection (e.g., precipitation and agglutination tests, ELISA (e.g.,Lateral Flow test or DAS-ELISA), Western blot, RIA, immuno labeling(gold, fluorescent, or other detectable marker), immunosorbent electronmicroscopy (ISEM), and/or dot blot), wherein one or more gene ormarker-specific antibodies are used to detect one or more desirableproteins. In one embodiment, said specific antibody is selected from thegroup consisting of polyclonal antibodies, monoclonal antibodies,antibody fragments, and combination thereof.

Reverse Transcription Polymerase Chain Reaction (RT-PCR) can be utilizedin the present disclosure to determine expression of a gene to assistduring the selection step of a breeding scheme. It is a variant ofpolymerase chain reaction (PCR), a laboratory technique commonly used inmolecular biology to generate many copies of a DNA sequence, a processtermed “amplification”. In RT-PCR, however, RNA strand is first reversetranscribed into its DNA complement (complementary DNA, or cDNA) usingthe enzyme reverse transcriptase, and the resulting cDNA is amplifiedusing traditional or real-time PCR.

RT-PCR utilizes a pair of primers, which are complementary to a definedsequence on each of the two strands of the cDNA. These primers are thenextended by a DNA polymerase and a copy of the strand is made after eachcycle, leading to logarithmic amplification.

RT-PCR includes three major steps. The first step is the reversetranscription (RT) where RNA is reverse transcribed to cDNA using areverse transcriptase and primers. This step is very important in orderto allow the performance of PCR since DNA polymerase can act only on DNAtemplates. The RT step can be performed either in the same tube with PCR(one-step PCR) or in a separate one (two-step PCR) using a temperaturebetween 40° C. and 60° C., depending on the properties of the reversetranscriptase used.

The next step involves the denaturation of the dsDNA at 95° C., so thatthe two strands separate, and the primers can bind again at lowertemperatures and begin a new chain reaction. Then, the temperature isdecreased until it reaches the annealing temperature which can varydepending on the set of primers used, their concentration, the probe andits concentration (if used), and the cations concentration. The mainconsideration, of course, when choosing the optimal annealingtemperature is the melting temperature (Tm) of the primers and probes(if used). The annealing temperature chosen for a PCR depends directlyon length and composition of the primers. This is the result of thedifference of hydrogen bonds between A-T (2 bonds) and G-C (3 bonds). Anannealing temperature about 5 degrees below the lowest Tm of the pair ofprimers is usually used.

The final step of PCR amplification is the DNA extension from theprimers which is done by the thermostable Taq DNA polymerase usually at72° C., which is the optimal temperature for the polymerase to work. Thelength of the incubation at each temperature, the temperaturealterations and the number of cycles are controlled by a programmablethermal cycler. The analysis of the PCR products depends on the type ofPCR applied. If a conventional PCR is used, the PCR product is detectedusing agarose gel electrophoresis and ethidium bromide (or other nucleicacid staining).

Conventional RT-PCR is a time-consuming technique with importantlimitations when compared to real time PCR techniques. This combinedwith the fact that ethidium bromide has low sensitivity, yields resultsthat are not always reliable. Moreover, there is an increasedcross-contamination risk of the samples since detection of the PCRproduct requires the post-amplification processing of the samples.Furthermore, the specificity of the assay is mainly determined by theprimers, which can give false-positive results. However, the mostimportant issue concerning conventional RT-PCR is the fact that it is asemi or even a low quantitative technique, where the amplicon can bevisualized only after the amplification ends.

Real time RT-PCR provides a method where the amplicons can be visualizedas the amplification progresses using a fluorescent reporter molecule.There are three major kinds of fluorescent reporters used in real timeRT-PCR, general non-specific DNA Binding Dyes such as SYBR Green I,TaqMan Probes and Molecular Beacons (including Scorpions).

The real time PCR thermal cycler has a fluorescence detection threshold,below which it cannot discriminate the difference between amplificationgenerated signal and background noise. On the other hand, thefluorescence increases as the amplification progresses and theinstrument performs data acquisition during the annealing step of eachcycle. The number of amplicons will reach the detection baseline after aspecific cycle, which depends on the initial concentration of the targetDNA sequence. The cycle at which the instrument can discriminate theamplification generated fluorescence from the background noise is calledthe threshold cycle (Ct). The higher is the initial DNA concentration,the lower its Ct will be.

Other forms of nucleic acid detection can include next generationsequencing methods such as DNA SEQ or RNA SEQ using any known sequencingplatform including, but not limited to: Roche 454, Solexa GenomeAnalyzer, AB SOLiD, Illumina GA/HiSeq, Ion PGM, Mi Seq, among others(Liu et al, 2012 Journal of Biomedicine and Biotechnology Volume 2012 ID251364; Franca et al., 2002 Quarterly Reviews of Biophysics 35 pg169-200; Mardis 2008 Genomics and Human Genetics vol 9 pg 387-402).

In other embodiments, nucleic acids may be detected with other highthroughput hybridization technologies including microarrays, gene chips,LNA probes, nanoStrings, and fluorescence polarization detection amongothers.

In some embodiments, detection of markers can be achieved at an earlystage of plant growth by harvesting a small tissue sample (e.g., branch,or leaf disk). This approach is preferable when working with largepopulations as it allows breeders to weed out undesirable progeny at anearly stage and conserve growth space and resources for progeny whichshow more promise. In some embodiments the detection of markers isautomated, such that the detection and storage of marker data is handledby a machine. Recent advances in robotics have also led to full serviceanalysis tools capable of handling nucleic acid/protein markerextractions, detection, storage and analysis.

Quantitative Trait Loci

Breeding schemes of the present application can include crosses betweendonor and recipient plants. In some embodiments said donor plantscontain a gene or genes of interest which may confer the plant with adesirable phenotype. The recipient line can be an elite line or cultivarhaving certain favorite traits such for commercial production. In oneembodiment, the elite line may contain other genes that also impart saidline with the desired phenotype. When crossed together, the donor andrecipient plant may create a progeny plant with combined desirable lociwhich may provide quantitatively additive effect of a particularcharacteristic. In that case, QTL mapping can be involved to facilitatethe breeding process.

A QTL (quantitative trait locus) mapping can be applied to determine theparts of the donor plant's genome conferring the desirable phenotype,and facilitate the breeding methods. Inheritance of quantitative traitsor polygenic inheritance refers to the inheritance of a phenotypiccharacteristic that varies in degree and can be attributed to theinteractions between two or more genes and their environment. Though notnecessarily genes themselves, quantitative trait loci (QTLs) arestretches of DNA that are closely linked to the genes that underlie thetrait in question. QTLs can be molecularly identified to help mapregions of the genome that contain genes involved in specifying aquantitative trait. This can be an early step in identifying andsequencing these genes.

Typically, QTLs underlie continuous traits (those traits that varycontinuously, e.g. yield, height, level of resistance to virus, etc.) asopposed to discrete traits (traits that have two or several charactervalues, e.g. smooth vs. wrinkled peas used by Mendel in hisexperiments). Moreover, a single phenotypic trait is usually determinedby many genes. Consequently, many QTLs are associated with a singletrait.

A quantitative trait locus (QTL) is a region of DNA that is associatedwith a particular phenotypic trait—these QTLs are often found ondifferent chromosomes. Knowing the number of QTLs that explainsvariation in the phenotypic trait tells about the genetic architectureof a trait. It may tell that a trait is controlled by many genes ofsmall effect, or by a few genes of large effect or by a several genes ofsmall effect and few genes of larger effect.

Another use of QTLs is to identify candidate genes underlying a trait.Once a region of DNA is identified as contributing to a phenotype, itcan be sequenced. The DNA sequence of any genes in this region can thenbe compared to a database of DNA for genes whose function is alreadyknown.

In a recent development, classical QTL analyses are combined with geneexpression profiling i.e., by DNA microarrays. Such expression QTLs(e-QTLs) describes cis- and trans-controlling elements for theexpression of often disease-associated genes. Observed epistatic effectshave been found beneficial to identify the gene responsible by across-validation of genes within the interacting loci with metabolicpathway and scientific literature databases.

QTL mapping is the statistical study of the alleles that occur in alocus and the phenotypes (physical forms or traits) that they produce(see, Meksem and Kahl, The handbook of plant genome mapping: genetic andphysical mapping, 2005, Wiley-VCH, ISBN 3527311165, 9783527311163).Because most traits of interest are governed by more than one gene,defining and studying the entire locus of genes related to a trait giveshope of understanding what effect the genotype of an individual mighthave in the real world.

Statistical analysis is required to demonstrate that different genesinteract with one another and to determine whether they produce asignificant effect on the phenotype. QTLs identify a particular regionof the genome as containing a gene that is associated with the traitbeing assayed or measured. They are shown as intervals across achromosome, where the probability of association is plotted for eachmarker used in the mapping experiment.

To begin, a set of genetic markers must be developed for the species inquestion. A marker is an identifiable region of variable DNA. Biologistsare interested in understanding the genetic basis of phenotypes(physical traits). The aim is to find a marker that is significantlymore likely to co-occur with the trait than expected by chance, that is,a marker that has a statistical association with the trait. Ideally,they would be able to find the specific gene or genes in question, butthis is a long and difficult undertaking. Instead, they can more readilyfind regions of DNA that are very close to the genes in question. When aQTL is found, it is often not the actual gene underlying the phenotypictrait, but rather a region of DNA that is closely linked with the gene.

For organisms whose genomes are known, one might now try to excludegenes in the identified region whose function is known with somecertainty not to be connected with the trait in question. If the genomeis not available, it may be an option to sequence the identified regionand determine the putative functions of genes by their similarity togenes with known function, usually in other genomes. This can be doneusing BLAST, an online tool that allows users to enter a primarysequence and search for similar sequences within the BLAST database ofgenes from various organisms.

Another interest of statistical geneticists using QTL mapping is todetermine the complexity of the genetic architecture underlying aphenotypic trait. For example, they may be interested in knowing whethera phenotype is shaped by many independent loci, or by a few loci, andhow those loci interact. This can provide information on how thephenotype may be evolving.

Molecular markers are used for the visualization of differences innucleic acid sequences. This visualization is possible due to DNA-DNAhybridization techniques (RFLP) and/or due to techniques using thepolymerase chain reaction (e.g. STS, SNPs, microsatellites, AFLP). Alldifferences between two parental genotypes will segregate in a mappingpopulation based on the cross of these parental genotypes. Thesegregation of the different markers may be compared and recombinationfrequencies can be calculated. The recombination frequencies ofmolecular markers on different chromosomes are generally 50%. Betweenmolecular markers located on the same chromosome the recombinationfrequency depends on the distance between the markers. A lowrecombination frequency usually corresponds to a low distance betweenmarkers on a chromosome. Comparing all recombination frequencies willresult in the most logical order of the molecular markers on thechromosomes. This most logical order can be depicted in a linkage map(Paterson, 1996, Genome Mapping in Plants. R. G. Landes, Austin.). Agroup of adjacent or contiguous markers on the linkage map that isassociated to a reduced disease incidence and/or a reduced lesion growthrate pinpoints the position of a QTL.

The nucleic acid sequence of a QTL may be determined by methods known tothe skilled person. For instance, a nucleic acid sequence comprisingsaid QTL or a resistance-conferring part thereof may be isolated from adonor plant by fragmenting the genome of said plant and selecting thosefragments harboring one or more markers indicative of said QTL.Subsequently, or alternatively, the marker sequences (or parts thereof)indicative of said QTL may be used as (PCR) amplification primers, inorder to amplify a nucleic acid sequence comprising said QTL from agenomic nucleic acid sample or a genome fragment obtained from saidplant. The amplified sequence may then be purified in order to obtainthe isolated QTL. The nucleotide sequence of the QTL, and/or of anyadditional markers comprised therein, may then be obtained by standardsequencing methods.

One or more such QTLs associated with a desirable trait in a donor plantcan be transferred to a recipient plant to incorporate the desirabletrait(s) into progeny plants by transferring and/or breeding methods.

In one embodiment, an advanced backcross QTL analysis (AB-QTL) is usedto discover the nucleotide sequence or the QTLs responsible for theresistance of a plant. Such method was proposed by Tanksley and Nelsonin 1996 (Tanksley and Nelson, 1996, Advanced backcross QTL analysis: amethod for simultaneous discovery and transfer of valuable QTL fromun-adapted germplasm into elite breeding lines. Theor Appl Genet92:191-203) as a new breeding method that integrates the process of QTLdiscovery with variety development, by simultaneously identifying andtransferring useful QTL alleles from un-adapted (e.g., land races, wildspecies) to elite germplasm, thus broadening the genetic diversityavailable for breeding. AB-QTL strategy was initially developed andtested in crops, and has been adapted for use in other crops includingrice, maize, wheat, pepper, barley, and bean. Once favorable QTL allelesare detected, only a few additional marker-assisted generations arerequired to generate near isogenic lines (NILs) or introgression lines(ILs) that can be field tested in order to confirm the QTL effect andsubsequently used for variety development.

Isogenic lines in which favorable QTL alleles have been fixed can begenerated by systematic backcrossing and introgressing of marker-defineddonor segments in the recurrent parent background. These isogenic linesare referred to as near isogenic lines (NILs), introgression lines(ILs), backcross inbred lines (BILs), backcross recombinant inbred lines(BCRIL), recombinant chromosome substitution lines (RCSLs), chromosomesegment substitution lines (CSSLs), and stepped aligned inbredrecombinant strains (STAIRSs). An introgression line in plant molecularbiology is a line of a crop species that contains genetic materialderived from a similar species. ILs represent NILs with relatively largeaverage introgression length, while BILs and BCRILs are backcrosspopulations generally containing multiple donor introgressions per line.As used herein, the term “introgression lines or ILs” refers to plantlines containing a single marker defined homozygous donor segment, andthe term “pre-ILs” refers to lines which still contain multiplehomozygous and/or heterozygous donor segments.

To enhance the rate of progress of introgression breeding, a geneticinfrastructure of exotic libraries can be developed. Such an exoticlibrary comprises a set of introgression lines, each of which has asingle, possibly homozygous, marker-defined chromosomal segment thatoriginates from a donor exotic parent, in an otherwise homogenous elitegenetic background, so that the entire donor genome would be representedin a set of introgression lines. A collection of such introgressionlines is referred as libraries of introgression lines or IL libraries(ILLs). The lines of an ILL cover usually the complete genome of thedonor, or the part of interest. Introgression lines allow the study ofquantitative trait loci, but also the creation of new varieties byintroducing exotic traits. High resolution mapping of QTL using ILLsenable breeders to assess whether the effect on the phenotype is due toa single QTL or to several tightly linked QTL affecting the same trait.In addition, sub-ILs can be developed to discover molecular markerswhich are more tightly linked to the QTL of interest, which can be usedfor marker-assisted breeding (MAB). Multiple introgression lines can bedeveloped when the introgression of a single QTL is not sufficient toresult in a substantial improvement in agriculturally important traits(Gur and Zamir, Unused natural variation can lift yield barriers inplant breeding, 2004, PLoS Biol.; 2(10):e245).

In the second year, the F₃ selection wasmade from the self-pollinated F2 plants in February, near Los Mochis,Mexico, in plot M31408 and the F₄ selection was made from theself-pollinated F3 plants in July near Coloma, Wis., in plot H306487. Inthe third year, the F₅ selection was made from the self-pollinated F4plants in February near Los Mochis, Mexico, in plot M40605 and the F₆selection was made from the self-pollinated F5 plants in July nearColoma, Wis., in plot H404011. In the fourth year, the F₇ generation wasbulked from the self-pollinated F6 plants in February near Los Mochis,Mexico, in plot M53292. In the fifth year, the F₈ generation was bulkedfrom the self-pollinated F7 plants in February near Los Mochis, Mexico,in plot M62848 and the F₉ generation was harvested from theself-pollinated F₈ plants as 100 single plants in September in TwinFalls, Id., in plot T604959.
